An aqueous KNO3 solution is made using 89.9g of KNO3 diluted to a total solution volume of 1.35L?
1.0 molal
What is the molality of a solution that contains 2 moles of glycerin and dissolved in 1000 g of water?
Moles of solute/ kg of solvent = 2 molal solution
What is the difference between partial molal quantities and partial molar quantities?
During the determination of the partial molal quantities the weight of the solution to which a substance is added is taken into consideration while in case of the partial molar quantity the volume is taken into consideration.
How many grams of HCl must be dissolved in 275.0 g of water to prepare a 1.5 molal solution?
The answer is 15,039 g hydrogen chloride (HCl).
How many moles of urea 60.0 g mol must be dissolved in 100.0g of water to give a 2.5 molal solution?
The answer is 15,015 g.
Is the molal and molar solution of NaCl the same?
yes
How 1 molal urea solution is equal to 0.5 molal NaCl solution?
Uric acid is an entirely different compound than salt, so I do not see how there is an equivalence between the two.
What is the boiling point of a 2.0 molal solution of glucose?
The boiling point is 101 oC.
An aqueous KNO3 solution is made using 89.9g of KNO3 diluted to a total solution volume of 1.35L?
1.0 molal
What mass of Kl is contained in 2.5L of water if the solution is labeled 2 molal?
Aprox. 830 g.
What is the molality of a solution that contains 2 moles of glycerin and dissolved in 1000 g of water?
Moles of solute/ kg of solvent = 2 molal solution
What is molal depression constant?
It is defined aste depression in freezing point of solution containing non-volatile solute.wen molality is equal to 1 and is caled molal depression constant i.e. Tf=kf . m
Which is more concentrated one molar NaCl or one molal NaCl?
They are equivalent. Molal is now an obsolete, not recommended term.
What mass of KI is contained in 2.5L of water if the solution is labeled 2 molal?
Approx. 830 g potassium iodide.
What is the difference between partial molal quantities and partial molar quantities?
During the determination of the partial molal quantities the weight of the solution to which a substance is added is taken into consideration while in case of the partial molar quantity the volume is taken into consideration.
What is the boiling point of a 2.47 molal solution of napthalene in benzenethe boiling point of benzene is 80.1?
the boiling point of platnium is 2500c
What are the materials for salt water freeze?
Salt lowers the freezing point of water by the amount of molals of NaCl in the solution. 0°C - 1.86(°C / molal) (NaCl molal). This will find the new freezing point and if the energy is enough to bring salt water below this temperature and turn the solution into ice then the salt water will freeze.
